HTML headings

Last update on August 19 2022 21:50:39 (UTC/GMT +8 hours)

1. From h1 through h6 (i.e. h1, h2, h3, h4, h5 and h6), HTML heading elements contain a heading for the content it precedes.

2. There are six levels of headings. h1, h2, h3, h4, h5, h6. h1 is the most important and h6 is the least.

3. When browsers display the content contained by HTML headings, the font size of text decreases in descending order (i.e. h1 has the largest, h6 has smallest).
But this should not be used for a variation of fonts. Headings should be used for serving the purpose they have created for.
